A-61140 January 2000 2-1

Selecting the language display

The scanner may have been configured at installation to allow use of a
second language in the status display. The language used (French,
German, Italian, Spanish, or other) is defined during installation. If
available, the alternate language display may be accessed using
function code F19.

Calibrating the scanner

Calibration sets the intensity of the lamps, which contribute to the overall
quality of the scanned document image.

The scanner should be calibrated:

• at least once a day

• if image quality is poor

• after changing lamps

Calibrate the scanner using a calibration target (sheet of paper) that is:

• Blank

• Clean

• Matte finish (not glossy)

• White or the same color as the background color of the documents

to be scanned. When using a duplex-defined application mode,
make sure that both front and rear colors of the calibration target
correspond with the front and rear colors of the documents to be
scanned. If you are scanning a variety of colored documents, use a
white calibration target.

• Wider than the documents you are going to scan (i.e., to scan 8.5 x
11 inch (216 x 279 mm) portrait orientation documents, the
calibration target should be wider than 8.5 inches (216 mm). The
recommended width for the calibration target is 12 inches
(300 mm).

To scan 11 x 17-inch (280 x 432) documents, the calibration target
should be wider than 11 inches (279 mm) but not wider than 12
inches (305 mm).

• Between 12 and 25.5 inches (305 and 648 mm) long.

For your convenience, 12 x 12-inch calibration targets
(Part # 986527) are supplied with the scanner and are also available
from Parts Services, 1 800 431-7278.

To calibrate the scanner:

1. Verify the power switch is on and a normal operating status display
is displayed.

2. Press CAL on the control panel. A message will be displayed
prompting you to feed the calibration target.

3. Insert the calibration target into the feeder.

When calibration is successful, the status display returns to a normal
operating display.

2-2 A-61140 January 2000

Unsuccessful calibration

If calibration is not successful, a message appears in the status display.
You may need to:

• Verify you are using a clean, blank sheet of paper (at least 12 inches
in length) as a calibration target. The paper must be wider than the
documents being scanned and at least 8 1/2 inches long.

• Verify there is not a document already in the document path. (Refer
to the section entitled, “Clearing the document path” in Chapter 7.)

• Clean the imaging guides. (Refer to the section entitled “Cleaning the
imaging guides” in Chapter 5.)

• Calibrate the scanner again. If calibration fails again, change the
lamps. (Refer to the section entitled, “Replacing the exposure
lamps” in Chapter 5.)

If you have done all of the above and calibration still fails, contact your
service representative.

Preparing documents for scanning

Document orientation

Document sizes

Before you begin processing documents, make certain the documents
may be fed through the scanner easily:

• Remove any staples, rubber bands, loose mending tape, or paper
clips from the documents to be processed.

• Straighten wrinkled edges and tape any torn documents.

• Trim ragged edges.

When using the semi-automatic feeder, make certain all documents are
of similar size, texture, thickness and weight, and the leading edges of
all documents are aligned.

Before scanning, position all documents the way you want them to be
displayed on the host computer. Feed the documents so the text or
graphic appears to be facing in the same direction.

The following document sizes can be scanned:
Length 2 ½ x 17 inches (64 x 432 mm). Documents between 17

and 30 inches (508 mm) long can be scanned by adjusting
the exit hopper end stops.

Width 2 ½ x 12 inches (64 x 305 mm)
Minimum document thickness: onion skin (0.0015-inch / 0.04 mm)
Maximum document thickness: index card (0.014 inch / 0.36 mm)

index card (0.040 inch / 1.00 mm)

A-61140 January 2000 2-3

Adjusting the feed
and separator roller
gap (semi-automatic

feeder)

The gap adjustment knob on the control panel increases or decreases
the space between the feed and separator rollers. The gap must be
adjusted properly for smooth transportation of documents without
document overlap.

When documents of different thicknesses are fed in a group, adjust the
gap using the thinnest document in the group.

The feed and separator roller gap may have to be adjusted to
compensate for:

• Very thin documents (onion skin, tracing paper, etc.).

• Very thick documents (card stock, punch cards, cover stock).

• Some coated documents (photographic paper, plastic-coated

paper).

If the gap is not adjusted properly:

• More than one document at a time may be drawn into the transport
system at the same time; not all of the documents will be scanned.

• Documents may be drawn into the transport too quickly; documents
may overlap or be spaced too closely (causing an error display).

• Documents may become skewed during transport; jamming may
occur.

NOTE:Prior to performing the adjustment procedure, the scanner

must be calibrated and enabled.

To adjust the feed and separator roller gap:

1. Verify that the power switch is on.

2. Turn the gap adjustment knob clockwise three complete turns to
open the gap between the feed roller and separator roller.

3. Enter F04 and enable Counting Only.

2-4 A-61140 January 2000

4. Press Run.

5. Select two documents of the same size, texture and thickness,
similar to the types of documents you will be scanning.

6. Place one document on top of the other. Hold the documents firmly
by their trailing edges. Insert them into the gap approximately 1/8 in.
(3 mm).

Bottom document
separates from
top document

7. If the documents separate, repeat the following steps until the
documents do not separate:

• Turn the gap adjustment knob clockwise 1/2 turn.

• Insert the documents again.

If the documents do not separate, proceed with Step 8.

8. Rotate the gap adjustment knob counterclockwise 1 or 2 clicks.
IMPORTANT: Do not make a gap adjustment while documents are

in the feeder or transport system; doing so will
produce an inaccurate adjustment.

9. Hold the trailing edges of the documents firmly. Insert them into the
gap.

• If the bottom document is not separating from the top document,

remove the documents and repeat Steps 7 and 8 until the bottom
document separates from the top document by approximately 1
in. (25.4 mm).

• If the bottom document is separating from the top document,

proceed with Step 10.

10. When you have adjusted the gap so the bottom document separates
consistently from the top document, rotate the gap adjustment knob
counterclockwise another 1 or 2 clicks to complete the adjustment.

11. Feed a stack of 50 to 100 documents twice through the transport
system. Verify the final count reflects the total number of documents
fed and that the counter shows the same amount each time the
documents are counted.

If the count is not the same, the gap is not adjusted correctly. Rotate

the gap adjustment knob counterclockwise another 1 or 2 clicks and
repeat Step 9. Repeat until corrected.

12. Press Stop.

position. For automatic feeding, raise the feed shelf to the 30° or 40°
position.

Adjusting the side guides

40° position

Before you begin feeding documents into the scanner, adjust the
position of the side guides and feed shelf position.

• Adjust the width of the feed shelf side guides to hold the widest
document you will be scanning. Leave approximately 1/16-inch
(2 mm) clearance on each side of the largest document to allow for
proper feeding.

NOTE: Ensure that the documents are center-fed so each

document covers the 2 ½-inch required width as indicated
by the label on the feed tray.

3 Operating the Scanner

Overview This chapter provides instructions for selecting modes, image level

settings and feeding documents using the semi-automatic feeder and
the automatic feeder.

The scanning process consists of the following steps:

1. Prepare the scanner for operation (refer to Chapter 2, Getting
Started for more information).

2. Select an application mode for the application.

3. Select the appropriate operating values required for the application
on the host computer.

4. Press the Run key.

5. Feed documents into the transport (refer to “Feeding Documents
using the semi-automatic (or automatic) feeder” later in this
chapter).

• The scanner assigns a sequential ID number, the document

image level and image address.

• The document is scanned.

• The document image header is created.

• The host computer initiates transfer of the document image

header and document image to the host system for storage on
magnetic or optical disk media.

• Documents are deposited in the exit hopper, face down, in the

order in which they were fed into the transport.

6. Press Stop to disable the transport after the last document has
been scanned or press End to alert the host computer that the batch
or job has ended.

NOTE: If Stop or End is pressed while scanning a stack of

documents, the feeder will stop. Any documents in the
transport system will be scanned and deposited face down in
the exit tray before the transport system is disabled.

A-61140 January 2000 3-1

Setting image levels Image levels are used to identify specific types of documents (or sets of

documents) for later indexing and retrieval. The image level assigned to
each document is inserted into the image header associated with the
document image.

There are four document image levels:

• Level 0

• Level 1

• Level 2

• Level 3

Setting Levels

Levels 1, 2, and 3 can be set by pressing a document Image Level key
on the control panel, or by using the optional Footswitch or Patch
Reader accessories.

Level 0 can be set by entering function code F07.

Selecting a mode The scanner offers 18 modes that may be programmed for a particular

application or group of applications.
When you select a mode for use with a particular application, you are

selecting the format/appearance of the output. Each mode is composed
of definitions that affect the output of the scanner. The required mode
definitions include language display, measurement format, index format,
image address rules, level rules, accessory status, etc.

The modes are programmed at the time of installation and stored for
easy access and use.

Many of the optional mode definitions set up during installation may be
overridden using function codes. The overrides are temporary, unless it
is specified during installation that the mode overrides are to be saved.

Detailed information regarding application modes, can be found in Kodak
publication, A-61097, Mode Setup Software.

Typically, the mode is selected via the host system, using a scanner­unique command. However, you may manually select a mode.

To select a mode do the following:

1. Enter function code F01 (Select Mode) by pressing the F key and the
numeric keys 0 and 1.

2. Press Enter.

3. Enter the desired mode number (modes range from 1 to 18).

4. Press Enter.

3-2 A-61144 January 2000

Temporary operating values

Each of the 18 modes programmed at the time of installation contain
definitions that affect the output of the scanner. Each mode is
programmed to conform to the output requirements of a particular
application or group of applications.

There may be instances, however, when a particular application requires
some variation of an existing mode. In such instances, mode definitions
may be changed using available function codes. See Chapter 4,
Function Codes, for a listing and description of the available function
codes.

NOTE: Changes to mode definitions remain in effect until another

mode is selected or the side panel switch is turned off. The
original mode definition is only affected by these changes if the
mode overrides are saved (the mode override option may be
selected at installation and if selected, a plus sign (+) appears
in the first line of the status display).

A-61140 January 2000 3-3

Feeding documents
using the semi­automatic feeder

Following are feeder instructions using the semi-automatic feeder. After
the scanner has been prepared for operation, the desired mode and any
temporary operating values have been defined, you are ready to feed
documents into the transport.

1. Verify that the power is on and that all of the proper adjustments
have been made (feeder side guides, exit hopper side guides, etc.).

2. Place the feed shelf in the Up position.

3. Select a stack of documents that is no more than 1.5 in. (38 mm)
thick. Hold the stack with the front sides facing up and the top of the
documents facing toward the scanner. Tap the bottom edge of the
stack against a flat surface so the documents are in an even bundle.

4. Fan the stack of documents so the leading edge of the top document
sticks out the farthest.

Fanned documents

5. Press Run.

6. Place the stack of fanned documents into the feeder so the leading
edge of the top document contacts the feed/separator rollers. The
documents are drawn into the transport, with the top document
being fed first. The documents are deposited in the exit hopper face
down, in the order in which they were fed into the transport.

NOTE: Be sure the documents are center-fed so each document

covers the 2 ½-inch required width as indicated by the label
on the feed tray.

Each document should automatically go into the feeder. If
the automatic flow is inhibited, gently push the top document
toward the feeder to re-establish automatic feeding.

40° position

Gap

release

To feed thick documents using the gap release lever:

1. Press down and hold the gap release lever; this opens the gap
between the feed and separator rollers allowing thick documents to
pass between them. You will be able to see the gap open as the
lever is pushed down.

2. Insert the thick document past the rollers until it is taken into the
transport system.

NOTE: If more than one thick document is to be scanned, feed

them into the transport one at a time.

3. After the thick document(s) have been scanned, release the gap
release lever; it will return to its original position. The feed and
separator rollers will return to their previously adjusted positions.

Feeding documents using the automatic feeder

Following are document feeder instructing using the automatic feeder.
After the scanner has been prepared for operation, the desired mode
and any temporary operating values have been defined, you are ready to
feed documents into the transport.

1. Verify that the power is on and that all of the proper adjustments
have been made (feeder side guides, exit hopper side guides, etc.).

2. Select a stack of documents that is no more than 1.5 in. (38 mm)
thick. Hold the stack with the front sides facing up and the top of the
documents facing toward the scanner. Tap the top edge of the stack
against a flat surface so the documents are in an even bundle.

3. Fan the stack of documents so the leading edge of the top document
sticks out the farthest.

4. Lift the feeder module and slide the top edge of the documents
underneath the feeder module. To help prevent multiple feeds, after
you place the documents under the feeder module, pull the
documents back slightly (about ¼-inch) from the separator roller.

5. Press Run.
NOTE: Be sure the documents are center-fed so each document

covers the 3 ½-inch required width.

6. As you scan documents, set the image level, as required, and
periodically remove documents from the exit hopper.

NOTE: When the image buffer is full, the feeder will turn off and the

image buffer status light will turn red. There may be a
momentary pause in scanning while images are being
transferred to the host computer. Scanning will resume and
the status indicator will change to green when the image
buffer is clear.

7. Repeat Steps 2 through 4 until all the application documents have
been fed into the transport.

8. Press Stop to disable the transport system after the last document
has been scanned, or press End to alert the host computer the
batch or job has ended and to disable the transport system after the
last document has been scanned.

Using the Bar Code Reader

The Kodak Digital Science Bar Code Reader provides a hands-off
method of data entry , eliminating the need to manually enter data found
on document(s). Bar code image(s) are read, decoded, and converted
to a data string of ASCII characters. The ASCII data string is placed in
the image header which is sent to the host computer when scanning, or
merged with the document image address and transmitted as a data
record to a host computer for storage in a data library when filming.

During installation, modes are defined for use with specific applications.
The Bar Code Reader may be enabled or disabled for each mode. In
addition, the bar code type, number of bar codes per document,
minimum bar code length (characters), and the distance between
multiple bar codes are defined for each mode.

This User’s Guide:

• explains what bar code types can be read and decoded by the
Kodak Digital Science Bar Code Reader.

• provides specifications that must be followed when placing bar
codes on documents.

• explains how to enable (or disable) bar code reading and the bar
code confirmation tone.

• explains how to perform a bar code test and how to use the three
test options — Evaluate, Display, Read Rate.

• provides information on how to evaluate test results.

For more detailed information about bar codes, see Kodak publication,
Bar Code Made Easy, A-61099.

A-61140 January 2000 8-3

Bar code types During installation, the type of bar code used is defined for each mode.

The Bar Code Reader is capable of reading and decoding three different
types of bar codes.

• Code 3 of 9 — also known as Code 39, is a widely used code in
which 9 bars or spaces comprise the characters, 3 of which are
wide.

• Interleaved 2 of 5 — or I 2 of 5, is a compact, interleaved code for
numeric characters only. Each digit is represented by 5 bars or
spaces, 2 of which are wide.

• Codabar — similar to Code 3 of 9, but not as widely used. Codabar
includes only numeric and special characters.

The following table shows a comparison of bar code types:

Bar code placement

Bar codes must appear with the bars perpendicular to the leading edge of
the document:

Leading edge
(fed into transport first)

Trailing edge

In addition, the following must be true:

• The bar code must be at least 0.25 in. (6.3 mm) from the leading
edge of the document.

• The bar code must be at least 0.25 in. (6.3 mm) from the trailing
edge of the document.

• There must be at least 0.25 in. (6.3 mm) of blank space preceding
the start character and following the stop character.

• The bar code may not exceed 11 in. (275 mm) in length.

• The bar code height must be at least 0.40 in. (9.5 mm) or 25% of the

bar code length, whichever is greater.

More detailed specifications are provided in Kodak publication, Bar Code
Made Easy (A-61099).

Before you begin Before feeding documents containing bar codes, verify the following:

• Bar code reading is enabled in the current mode.

• The bar code confirmation tone is enabled (if desired).

• A bar code test has been performed and the read rate/accuracy is

satisfactory.

Once each of these items has been verified, you may begin feeding
documents.

A-61140 January 2000 8-5

Enabling bar
code reading

Make sure that Bar Code Reading is enabled before feeding
documents.

To enable Bar Code Reading at the mode level:

• Enter function code F60.

If you have enabled the Bar Code Reader, but do not want to
read/decode bar code(s) found on the next document only, perform
function code F64.

Enabling the bar
code confirmation
tone

The bar code confirmation tone may be used to signal that a bar code
has been read.

• If your machine is configured for no confirmation tones, then no
confirmation tones of any kind will be heard in any mode.

• If your machine is configured to allow confirmation tones, then you
can disable (or enable) confirmation tones in any mode as desired.

If the machine confirmation tones and the bar code confirmation tone
are enabled during installation for the mode being used, you may
enable/disable the bar code confirmation tone during normal
operations by performing function code F63.

In addition, a bar code/patch code confirmation tone may be used to
signal that both a bar code and a patch have been detected. This
confirmation tone may be enabled or disabled by performing function
code F62.

NOTE:Patch Code Reading must be enabled in the scanner in order

to use this feature.

8-6 A-61140 January 2000

Performing a bar
code test

Before feeding documents, perform a bar code test (F65) to verify the
operation of the Bar Code Reader.

NOTE:No document processing, image address changes or level

counting, etc. will occur during the test.

To perform a bar code test , select one of the test options.

1. Enter function code F65.

2. Select one of the following options.

BC Type =
1: EV 2: DP 3: Rr

• 1=EVALUATE (1: EV) — provides a measure of the overall

quality of the bar codes being used by evaluating specific bar
code characteristics. This test is performed whenever a new
batch of preprinted bar code documents or labels are received,
or when there is a change in the printing method (i.e., a new
printer), media (i.e., new paper type) or bar code characteristics
(i.e., new bar code size).

• 2=DISPLAY (2: DP) — displays the decoded value of an

individual bar code as it is fed into the transport. This test is
performed whenever there is a need to verify that a bar code is
decoded properly. The bar code is read and decoded. No
capturing of images or any other system function is performed
when this test is run.

• 3=Read Rate (3: Rr) — provides a measure of equipment

performance by determining the read rate (percentage of bar
codes read properly) of Kodak Bar Code Standard Test
Documents. Two percentages are calculated each time the test
is run; a current percentage and a historical percentage. The
historical percentage reflects all tests run, providing information
which may be used to track system performance over time.

A-61140 January 2000 8-7

Function code F65 options may also be used if there is a decline in bar
code readability (read rate) during normal document processing. If this
occurs, the following steps will assist you in diagnosing the problem:

1. Perform test option 3=Read Rate.
This test determines whether or not the reduction in readability is
caused by a deficiency in the equipment.

− If the resulting read rate is significantly lower than the benchmark

given, contact Service.

− If the resulting read rate is equal to or greater than the

benchmark given, proceed to Step 2.

2. Perform test option 1=EVALUATE.
This test evaluates the bar codes being used in terms of
dimensional and print clarity. Deficiencies in any one or more of
these criteria could result in a reduction in the overall read rate.

Using the Evaluate
option

Use the Evaluate option when you want to measure the quality of the bar
codes being used by evaluating specific bar code characteristics.

To use the Evaluate option:

1. Select 1: EV.

BC Type =

Evaluating test results

The results of the Read Rate test will tell you how well your Bar Code
Reader is working. The following descriptions and tables will help you
determine the results of the bar code test.

Dimensional Fields (Pass or Fail)
W/N — the average ratio of wide element widths to narrow element

widths within a bar code. The ratio is calculated for both bars and
spaces; the smallest of the two ratios is displayed.

New — the measure of the smallest Narrow-Element Width.

Reflectance Fields (Grades A through F)
RMIN — minimum reflectance . A measure of the lightest element of the

bar code.
Contrast — a comparison of the darkest and lightest element of the bar

code.
MOD — Modulation. A measure of the consistency of the overall bar

code print clarity (all elements), specifically the occurrence of spots (in
spaces) and voids (in bars).

DEF — Defect ratio. A measure of the consistency of the individual
element print clarity, specifically the occurrence of spots (in spaces) and
voids (in bars).

Grade — indicates the overall grade of the bar code evaluation. This
grade is based upon the field values that appear in the remainder of the
display. The fields which appear in the remainder of the display are
either dimensional or reflectance fields.

Each of the reflectance field values are converted to a letter grade
(where A is the highest and F is the lowest). The lowest letter grade
assigned to any one of the reflectance fields is the overall grade
assigned to the bar code.

8-14 A-61140 January 2000

Table 1 illustrates how the dimensional field values are converted to a
pass/fail status and the print clarity field values are converted to letter
grades:

When finished, the percentage (%) indicates the read rate of the
documents just processed.

NOTE:To stop the test and leave the percentages unchanged, press

Stop before the 100 documents have been processed.

• If using the Kodak Bar Code Standard Test document — if

the read rate is significantly lower than in the past, this could be
caused by a deficiency in the equipment. Perform required
maintenance and rerun the test. If the results of the second test
are similar to the first, contact Service.

• If using customer application documents — if the read rate is

significantly lower than in the past, this could be caused by a
deficiency in the bar code quality. Perform the Evaluate option to
determine the cause of the test results.

3. When the test is finished, press C to return to normal operation, or
press Stop to remain in the test environment.
